Would you rather discover alien life or an animal that was thought to be extinct?

Vikentia [17]

$\boxed{I\; would\; say\; an\; animal\; that\; was\; thought\; to\; be\; extinct.}$

The reason i say this is because i don't really want to run into something that i don't know much about. I do know quite a bit about extinct animals more than i do aliens. So, that's my reasoning.

It is given 5 and h + 1 are the roots of the quadratic equation x² + (k - 1)x - 5 = 0,where h and k are constant.Find the value

Liono4ka [1.6K]

Answer:

Hello,

k=-3 and h=-2

Step-by-step explanation:

$5\ is\ a \ root \of \ x^2+(k-1)*x-5=0\\\\5^2+(k-1)*5-5=0\\\\5*(k-1)+20=0\\\\k-1=\dfrac{-20}{5} \\\\k=-4+1\\\\\boxed{k=-3}\\$

h+1 is thus a root of x²+(-3-1)*x-5=0

x²-4x-5=0

x²+x-5x-5=0

x(x+1)-5(x+1)=0

(x+1)(x-5)=0

h+1=-1

h=-2

Need Help on this assignment ASAP!

allsm [11]

The answer is y=(1/2)x -5

You are given the slope and a core donate pair so you plug them in to the equation. 2=x. -4=y. And (1/2)= m

Then work out like a one step equation

A 600-ft tall building is represented by a 30-in. tall model.

alexdok [17]

$\huge\boxed{19\ \text{inches}}$

First, find the scale factor by dividing the first building's real-life height by its model height.

$\frac{600}{30}=\frac{60}{3}=20$

Now, we'll write an equation to find the model height of the second building.

$r=20m$

Here is an equation where $r$ represents the real-life height of a building, $20$ represents the scale factor, and $m$ represents the model height of the same building.
